A BUNK FOR A VEHICLE CAB

The bunk (1) comprises: - a frame (10) attached to the cab, having a front beam (2) a rear beam (3) and side beams (4), each side beam comprising a front segment (41) and a rear segment (42), - a supporting structure (50) coupled to the frame and extending over the inner surface (5) of the frame. [0002] The bunk can change: - from a normal state, in which the front and rear beams are spaced apart by a nominal distance Dn, the front and rear segments being in a first relative position, - to a collapsed state in which the front and rear beams are spaced apart by a distance D < Dn, and in which the front and rear segments are in a second relative position
